I love this cake and am wondering what tip is used to do the sides of the cake and how its done. I *think* its a small rose tip but wanted to ask the pros. Thanks!

I think you are quite right about the rose tip!

Maybe a flat sided basketweave tip.

I think it might be tip 150. It looks very similar to the rose tip but it's even. The opening is one size not big to small like the rose tip.

I think either the 150 or a flat sided basket weave tip would do the trick.

I vote for a basketweave tip too. In fact, you wouldn't even have to try to make the wavy lines. You could just apply pretty heavy pressure and it'll probably naturally do that.
